SASH-OI-PERATING MECHANISM.

Specification of Letters Patent. Patented NOV. 23, 1909..

Application filed October 1.4, 1909. Serial, No. 522,585.

Be it knownthat I, STEPHEN E. CIBULAS, a citizen of the United'States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvementin Sash-Operating Mechanism, of which the following 1s a specification.-

This' invention has for its object to provide simple, inexpensive and easily operated mechanism for simultaneously openin'gand closing a plurality of swinging windows, as

for example the cupola windows of a factory, and that shall provide an operating rod for each side of each window except the end ones, thereby insuring smooth and easy operation of the windows as binding is prevented.

My invention furthermore has for its object to provide low fusing connections between the operating rods and the operating shaft that will yield should thetemperature be abnormally raised, as in case of fire, thereby disconnecting the windows from the operating shaft and permitting them to swing to the closed position by gravity without operation of the shaft.

With these and other objects in view my invention consists in certain constructions and in certain parts improvements and combinations which will be hereinafter described and then specifically pointed out in the claims hereunto appended.

In the accompanying drawings forming a part of this specification, Figure 1 is a horizontal section of a series of windows in the closed position, on the line 1l inFig. 4, showing the operating mechanism in plan, an open position of the windows being indicated by dotted lines; Fig. 2 anenlar-ged detail view partly in section on the line 2-2 in Fig. 1 looking in the direction of the arrow; Fig. '3 a view as seen from the left in Fig. 2; Fig. 4 an elevation showing the construction of my novel operating mechanism and its application to a series of windows; Fig. 5 an enlarged detail view, the cross bar being in section on the line 5-5 in Fig. 4 looking in the direction of the arrow; Fig. 6 an enlarged detail view, the operating shaft being in section on the line 6-6 in Fig. 4 looking in the direction of the arrow; and Fig. 7 is a view corresponding with Fig. 2 illustrating a variant form in which provision is made for the releasing of the windows, permitting them to automatically close by gravity in the event of a fire.

' Fig. 4

10 denotes the wall of a building and 11 windows pivoted as at-12 to swing in casrods are adjustably connected to a cross bar 16. The connection of the operating rods to the cross bars may be made in any ordinary or preferred manner. In the drawings I have shown guides 17 which are rigidly secured to the cross bars through which the operating rods pass and to which said rods are locked by set screws 18 thereby permitting adjustment, (see Fig. 5 in connection with Fig. 4).

19 denotes a longitudinally movable operating shaft, in the present instance shown as a tube, which slides in suitable guides 20 secured to the casing. The guides are preferably provided with anti-friction bearings (not shown) for the shaft. The shaft is provided with a rack 21 which is engaged by a pinion 22 carried by a short shaft 23 which also carries a pulley 24'over which an operating rope25 passes. Shaft,23 is mounted to rotate in a bracket 26 which may also serve as a guide for the operating shaft. The cross bars are connected to the operati'ng shaft at their mid-length by means of operating links 27.

29 denotes brackets which are pivoted. to the outer ends of links 27,- as at 28, and are provided with'eyes 30 through which the cross bars pass and in which they are free to oscillate. The brackets are connected to the cross bars by means of screws 31 which pass through slots 32 in the eyes and engage the cross bars (see Figs. 2 and 3 in connection with Fig. 1).

33 denotes links the ends of which are pivoted to the mid-length of links 27, as at 34, and to fixed supports, in the present instance to uides 20, in alinement with the pivotal points of links 27 to the cross bars, as at 35. The inner ends of links 27 are connected to the operating shaft by means of yokes 36, the arms of which straddle the shaft and are looked thereto by means of bolts 37. The yokes are shown as provided with bosses 38 to which links 27 are pivoted as at 39, (see Fig. 6 in connection with Links 27 and 33 are shown as angle links for the purpose of securin ample strength with the least weight an material although the special shape ofthe links is wholly immaterial so far as the principle of the invention is concerned. The ends of the operating shaft may be sup-- ported in any ordinary or preferred manner. I have shown one end of the operating shaft, in the present instance a tube, as sliding over a guide rod which extends from a base plate ll which is secured to the wall.

' It will be noted as an important feature of the invention that each cross bar is operated by means of a single link extending from its mid-length to the operating shaft and that two operating rods are connected r to each cross bar, said operating rods being connected to the contiguous side rails of "difierent windows so that each'window except the two end windows is controlled by a two operating rods. 1 thus insure perfectly easy and smooth operation of the windows nst-here can be no lateral pressure that would pause them tobind in the casings.

entire series ofwindows the operator simply pulls upon one side or the other of the oper 1 roperotating short shaft 23 and movmg-1e18, operatin shaft longitudinally by mea'nsfof the mo. and pinion. When the operating shaft is moved toward the right as seen in the drawing,- operatrng links 27 will be drawn inward, which Wlll draw the cross bars and operating rods inward and 'will swing windows to the; open position,

as'illdicated "by dotted lines in Fig. 1, the eperation of links 33 being to prevent lateral movement'and to insure direct inward move ment of the cross bars and operating rods so that the windows will swing perfectly freeiy; When the operating shaft is moved toward the left the operating links and links 33 will be moved from the dotted to ward the full line position shown in Fig. 1

"bars and operating'rods from the operating and the windows may be moved to the closed position as shown in full lines in said In the form illustrated in F ig. 7, I provide a low fusing connection between the cross bars and the operating links, which will bemclted in the event of an abnormal risein temperature and release the cross linkshnd will permit the windows to close automatically-by gravity without operation of the operating shaft. In this form the cross bars are secured to a two-part bracket 42 in the same manner as before. The two Jf he operation-will be perfectly obvious dem the drawing. To open or close, the

solder, the weight of the window; when in two-part bracket is as rigid as the other form, the sleeve being securely attached to the rod by the solder and the two parts of the bracket being rigidly secured together by tightcneing up the nut.
